Welcome to my practice git repository where you can eff up as much as you'd like plus work with a real, living, breathing person on the other side. Here we learn all things git. Feel free to send me Pull Requests just to discover what it's like when a Repo Master asks you
"Can you squash your commits for us"
and you're all like...
"How the hell do I do that?"
This is where we make those mistakes ... so don't be scared :)
Fork this repo and send me a Pull Request with anything from Grandma Peggy's Crumbled Oatmeal Cookie Recipe to your favorite Sublime Text 2 preferences. It's all good yo! Learning is the prize in this game.
Typical & Highly Useful Git Commands
git clone email@example.com:<user_name>/the-repo-you-are-cloning.git
Clones your remote origin repo locally
git fetch upstream
Pulls in the remote changes not present in your local repo. Downloads objects and references from another repository.
git merge upstream/master
Merges any changes fetched into your working files
git add <file>
Start tracking new files and also stage changes to already tracked files
git status &
- Tells us what files and assets have been modified and staged
git status -s
This will display what files have been removed, changed or modified.
- (M) - modified
- (A) - added
- (AM) - file has not been altered since it was last added
git commit -m 'the message goes here for the commit'
Records a snapshot of the project into your history at the time of your commit.
git add '*.<file_extension>'
This command adds all file types with the same extension, especially from different directories. Without quotes the command will only execute within the same directory it's been called from.
git rm --cached <file>
Unstages a file from the working tree (i.e. stops tracking the file).
Remembers all the changes we've committed so far, in the order we committed them.
git log --summary
See where new files were added for the first time or where files were deleted.
git remote add origin firstname.lastname@example.org:<user_name>/<repo_name>.git
Creates a brand new remote repository.
git remote -v
Show a list of the current remote repositories
git reset <file>
Removes the desired file from staging area.
git branch -r
List all the remote branches currently tracked
git remote prune origin
Deletes branch locally if it has been removed remotely. Helps to remove stale references.
git checkout -- <target>
Changes the desired target back to the state of the last commit. A target can be a file or a directory (for example).
Be warned: it's considered bad practice to rebase commits which you have already pushed to a remote repo. Doing so may invoke the wrath of the git gods. https://help.github.com/articles/interactive-rebase
git add <list of files>
git add readme.md license.txt. Can be multiples)
git add --all
Add all the new files since last
git add *.txt
Add all txt files in directory
Show unstaged differences since last commit
git diff --staged
Gets the staged differences and displays what has changed since our last commit
git reset HEAD <file>
Head is the last commit on the current branch we are on. What if you stage something you didn't need to be staged? This is the key.
git checkout -- <file>
Reset all changes to a file since last commit
git reset --soft HEAD^
What if you regret a commit? This will undo your last commit. (^ means move commit before HEAD and puts changes into staging).
git reset --hard HEAD^
Traverse through commits and revert back one by one.
git reset --hard HEAD
Undo Last commit and all changes
git commit --amend -m "added another file to the commit'
New commit message will override previous commit message

git remote add <name> <address>
Add a new remote repo
git remote rm <name>
Remove remote repo
Cloning, Branching, Fetching & Merging
Pulls down any changes but doesn't merge them
git branch <branch name>
Makes a new branch
git checkout <branch name>
Switching branch and on a different timeline
git merge <branch>
Merges branch into master
git branch -d <branch name>
git checkout -b <branch name>
Creates a new branch and then switches to it
:wq + enter
VI Editor Quick Key Exit
g fetch origin git checkout -t <remote>/<branch>
Fetches a remote branch not available locally also reference issue #7
Pushing & Pulling
git push -u origin master (remote repo name[origin], local branch name[master])
Lets you just run git push later on without specifying name and branch
Pull changes in and syncs up your repo. Doesn't update local code
git branch -r
List all remote branches
git remote show origin
Show all the remote branches
git push origin :<branch name>
Deletes the remote branch
git branch -D <branch name>
Delete the local repo branch and if you don't want the commits any longer on it then delete them too.
git remote prune origin
Deletes the branch locally if it has been removed remotely. Helps to remove stale references.
"Merge commits are bad"
Move all changes to master local which are not in origin/master remote to a temporary area
Viewing the commits history
git config --global color.ui true
Color codes the commit SHA
git log --pretty=oneline
git log --graph --oneline --all
Commit and history is one line
git log --pretty=format:"%h
